It's been possible to maintain some less played toons or alts viability by playing difficult content like raids. Usually that meant better gear.
That option has kinda been lost - ironically the most efficient way of character progress is NOT group based difficult content but actually zerging easy content like low skull heroics.
Would it make sense to double epic base reaper xp and double the skull contribution ? Give option to people that just don't wanna tr or don't have really time to tr anymore ?
Some incentive to crank up the skulls.
Something like skull 2 - 3 heroic Gianthold - that is rather trivial to solo giving same xp as 8+ skull epic Black and Blue ( repeat ) ?
It's not even in the same ballpark, difficulty and time wise.
Elementary principle in gaming - step up your game and you'll get rewarded. In that kinda sense.
